TILTING TANK FOR RECEIVING OR DISCHARGING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 621,982, dated March28, 1899.

- I Application filed May 5, 1898. Serial No- 679,807. (No model.)

To all whom it may concern:

Be it known that I, GEORGE T. TILDEN, a citizen of the United States,residing in Milton, in the county of Norfolk and State of Massachusetts,have invented a new and Improved Tilting Tank for the Reception orDischarge of Liquids, of which the following is a specification.

This construction comprises a tank for receiving, holding, anddischarging water or other liquid, the said tank comprising two separateand distinct chambers similar in form, but reversed in position relativeto each other. The tank is sustained upon a knifeedge or other suitablepivotal support, so'

that it may be readily tilted from one side to the other without losingits proper relation to the supply-duct, which is located centrally aboveit. The two chambers are separated by a partition common to both, andthis partition is centrally formed into oppositely-inclined troughs orguideways set side by side and leading into their respective chambers,thus converting a small portion of the dividing-wall between the tanksinto a partition between and common to .both of the troughs, suchpartition running at right angles to .the long axis of the double tank.

WVhen the supply-duct is properly located above the tank, its dischargeis received by one or the other of the troughs, and'thence.

conducted into one or the other of the chambers, according to theposition of the tank, the chamber receiving the inflow of liquid beingthat which is uppermost. When the liquid thus received in this chamberhas reached such a level as to overbalance the tank, the said chamber istilted down by gravity and discharges its contents, thus swinging up theother chamber into position to receive the' inflow, and the process justdescribed is repeated by the latter chamber. Thus the tank receives theliquid into its chambers alternately and discharges such liquidintermittently-that is to say, from the chambers alternately and atopposite ends of the tank.

This is accomplished without the employment of 'siphonic action, as wasthe case in the invention described in Letters Patent of the UnitedStates, numbered 576,006, granted to me January 26, 1897.

This improved tilting double tank may be used in supplyingwater towater-closets, for emptying receptacles containin sewage, and

in many other positions and conditions where a strictly-speakingintermittent, but practically (if desired) continuous, discharge ofwater or other liquid is required.

Among the objects of this improvement are the prevention of cloggingwhich is often incident to the employment of siphon-tubes and economy ofconstruction.

The nature of my invention is fully described in detail below andillustrated in the accompanying drawings, in which- Figure 1 is aperspective View of my improved double tilting tank with one chamber inposition for receiving the inflow and the other chamber in position fordischarging. Fig. 2 is a longitudinal vertical section taken on line X,Fig. 1. In this figure the location of the supply-duct is indicated, andbroken lines illustrate the position of the tank when tilted in thereverse direction.

Similar letters of reference indicate corresponding parts.

A and B represent, respectively, the outer walls of two similar tanksplaced side by side and rigidly connected or united, but so set withrelation to each other that the discharge end of each tank projectsbeyond the opposite end of the other tank.

0 represents a substantially vertical partition between and common toboth tanks. By this means the two tanks are united, so as to constitutea double tank with two distinct and separate chambers. At 0 and 0 thispartition extends beyond the deeper or inner ends of the chambers andconstitutes walls of the discharging ends of the chambers.

D represents the bottom of the tank, such bottom being common to the twochambers. This bottom is transversely bent or formed upward at D, so asto constitute an obtuse angle substantially as shown, and the undersurface of said bottom is preferably thickened at D and transverselygrooved at D in order that the tank may be sustained centrally by aknife-edge or pivotal support S. The upper edges of the walls A B areformed at A B into angles which substantially correspond with the angleof the bottom D, and the upper edge of the partition 0 O 0 follows thesame angle as the upper edges of the walls A B. The inner end of each ofthe reversely-set chambers is provided with an end wall E, which ispreferably substantially at right angles with theside walls A B and theadjacent portions of the bottom. At the opposite end of each of saidchambers the floor is formed at d at an obtuse angle into an end wall F,which when that end of the tank is tilted down lies in a substantiallyhorizontal position or extends down slightly from such position andserves to discharge the liquid from its chambers.

The partition 0 is formed centrally into the two oppositely-extendingtroughs or guideways H and H, said troughs extending, preferably, downto the floor or bottom D and being separated by the partition-wall H",common to both troughs, extending transversely with the tank and locateddirectly over the pivotal point of the bottom of the tank when the tankis exactly balanced. The deep end of each chamber-that is to say, theend between the end wall E and the points A and Bis provided with asuitable cover K, which is preferably cemented or otherwise secured inposition, so as to make a water tight joint. These covers preferablyextend to the points A and B, and hence conform in shape to the troughswhich are formed in the partition C.

The tank being in the position indicated in the drawings, water orliquid from the duct Y flows into the trough H and thence into thecha1nber,which is shown in full lines in the drawings as beinguppermost. When the liquid in this chamber has reached a sufficientlevel, the tank is overbalanced and tilts into the position indicated bybroken lines in Fig. 2. In this latter position the water which hasflowed into the forward chamher is quickly discharged over the inclinedpartition F, which is in a substantially horizontal position. Meanwhilethe trough H is under the duct Y and the water is conducted by saidtrough into the rear chamber, which when the liquid has reached asufficient level tilts down again into the position indicated in fulllines in the drawings, discharging the water over the portion F. Thus acontinuous stream of water from the duct Y flows alternatelyinto thefront and rear chambers, and the liquid is discharged intermittentlyfrom the opposite ends of the tank quickly in large volumes an d withoutdanger of any portion of the apparatus becoming clogged. Ofcourse thesedischarges may be brought to a common outlet or led oft" into diderentdirections, as desired.

While this device is intended, primarily, for the reception anddischarge of liquids, any other flowing materialsuch as seeds, shot,&c.which will pass through the tank by the action of gravity may beapplied to it.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. Atilting tank of the character described, comprising two distinct andrigidly-connected chambers similar in form but relatively reversed inposition and so set with relation to each other that admission of liquidinto one chamber tends to overbalance the other,

said tank being provided with a bottom ex tending across and common tothe chambers and formed substantially into two longitudinal planesmeeting each other at an obtuse upward angle, one end of each of saidchambers projecting beyond the opposite end of the other chamber andbeing provided with the end wall F set at such an angle that when saidend is tilted down the end wall F will lie in a substantially horizontalposition and thus discharge the contents of the chamber, the tank beingadapted to be supported pivotally at substantially the point where thetwo planes of the bottom meet, substantially as described.

2. Atilting tank of the characterdeseribed, comprising two distinct andrigidly-connected chambers separated by the partition 0 and relativelyreversed in position, said chambers being provided with the commonbottom D formed substantially into two longitudinal planes meeting at Dat an obtuse upward angle, said chambers being each provided with aclosed deep end formed by said bottom, the partition 0, outer walls Aand B respectively, deep end wall E, and cover K, and being eachprovided with an open end formed by said bottom, the extensions C and 0respectively of the partition C, the outer walls A and B respectively,and the end wall F set at such an angle that when the open end is tilteddown the end wall F will lie in a substantially horizontal position andthus discharge the contents of the chamber, the tank being adapted to bepivotally supported at substantially the point where the two planes ofthe bottom meet, substantially as set forth.

3. Atilting tank of the character-described, comprising two distinct andrigidly-connected chambers separated by the partition 0 and relativelyreversed in position, said partition being formed centrally into the twooppositely-set troughs H and H respectively extending into and to thebottoms of the said chambers,- and said chambers being provided with thecommon bottom D formed substantially into two longitudinal planesmeeting at D at an obtuse upward angle, said chambers being eachprovided with a closed deep end formed by said bottom, the partition'C,

1 outer walls A and B respectively, deep end wall E, and cover K, andbeing each provided with an open end formed by said bottom, the
